Researchers found phospholipids to be essential in epithelial cell adhesion. Phosphatidylinositol bisphosphate (PIP2), a phospholipid, is essential for epithelial cell-cell adhesion and maintaining cellular identity. Body cells in multicellular organisms adhere to one another to form tissues that perform various physiological functions. Epithelial cells form our skin and lining surfaces, such as the gut and other ducts, and protect our internal organs. Epithelial cells are a type of cell that lines the surfaces of your body. They are found on your skin, blood vessels, urinary tract, and organs. To maintain the integrity of an organism and function properly, it is important for these cells to remain attached to each other. They do so through specific types of cellular junctions. These junctions are characterized by proteins, which also help in maintaining cellular identity. The Epithelial-Mesenchymal Transformation (EMT) The loss of these proteins from cell surfaces causes them to lose their identity as epithelial cells, prompting their transformation into mesenchymal cells (through a process known as epithelial-mesenchymal transformation, or EMT), and subsequently, their progression towards cancer and fibrosis. These cancerous cells are only loosely adherent to each other (given that the proteins that helped maintain cellular adhesion are now lost), so they may separate from each other, migrate into the bloodstream, and cause the cancer to metastasize (spread to other parts of the body). Lipids in Cellular Identity Now, while the role of proteins in maintaining cellular identity is well-researched, we can’t help but wonder–do lipids (fatty molecules) also play a role in characterizing cells and preventing EMT? Under the guidance of Dr. Yoshikazu Nakamura and Dr. Kaori Kanemaru, scientists from Tokyo University of Science (TUS), Tokyo University of Pharmacy and Life Sciences, Tokyo Medical and Dental University, Akita University, Hokkaido University, and Kobe University have tried to find an answer to this question. The phospholipid PIP2 plays a critical role in maintaining the characteristics of epithelial cells. Credit: Yoshikazu Nakamura from Tokyo University of Science “We know lipids are an important class of biomolecules, necessary for certain cellular functions. One such lipid, a phosphatidylinositol, forms a phospholipid called phosphatidylinositol bisphosphate (PIP2),” Associate Professor Dr. Nakamura from TUS dives into the topic. He tells us that PIP2 is important because it is crucial for the formation of signaling molecules that regulate cell proliferation, survival, and migration. “We had evidence that higher amounts of PIP2 were found in the epidermal layer of skin, so we hypothesized that this phospholipid contributed to the properties and characterization of epithelial cells.” PIP2’s Role in Epithelial Cell Properties The findings from their study will be published in the journal Nature Communications today (May 9, 2022). The paper describes how the team used a battery of analytical techniques including chromatography, mass spectroscopy, immunofluorescence, retroviral expression, and real-time quantitative PCR to confirm that PIP2 plays a critical role in the determination of epithelial identity. “We saw that epithelial cells lost their properties when PIP2 was depleted from their cell membranes. On the other hand, osteosarcoma cells (which are cancerous, non-epithelial cells) gained epithelial cell-like properties when PIP2 was produced in their plasma membranes,” says Dr. Nakamura, with a look of excitement. The group was also able to show that PIP2 regulates these epithelial properties by recruiting Par3—a protein that guides vesicles intracellularly—to the plasma membrane. Once in the plasma membrane, Par3 facilitates the formation of adherens junctions (one of the cellular junctions discussed above) which anchor neighboring cells together. This partially prevents EMT, and hence, progression of cancer. “So,” Dr. Nakamura explains, “In theory, PIP2’s partial inhibition of EMT could halt cancer progression, making this phospholipid an attractive target molecule for anti-cancer treatment.” TUS’ research has opened a new avenue for the development of anti-cancer drug development, possibly giving us a solution that will “stick.” Reference: “Plasma membrane phosphatidylinositol (4,5)-bisphosphate is critical for determination of epithelial characteristics” by Kaori Kanemaru, Makoto Shimozawa, Manabu Kitamata, Rikuto Furuishi, Hinako Kayano, Yui Sukawa, Yuuki Chiba, Takatsugu Fukuyama, Junya Hasegawa, Hiroki Nakanishi, Takuma Kishimoto, Kazuya Tsujita, Kazuma Tanaka, Toshiki Itoh, Junko Sasaki, Takehiko Sasaki, Kiyoko Fukami and Yoshikazu Nakamura, 9 May 2022, Nature Communications.

Clustered fruit fly nurse cells squeeze their contents into a large egg cell. Credit: Jasmin Imran Alsous Oocyte growth relies on physical phenomena that drive smaller cells to dump their contents into a larger cell. Egg cells are by far the largest cells produced by most organisms. In humans, they are several times larger than a typical body cell and about 10,000 times larger than sperm cells. The researchers showed that “nurse cells” surrounding the much larger oocyte dump their contents into the larger cell, just as air flows from a smaller balloon into a larger one when they are connected by small tubes in an experimental setup, as shown here. Credit: Courtesy of the researchers There’s a reason why egg cells, or oocytes, are so big: They need to accumulate enough nutrients to support a growing embryo after fertilization, plus mitochondria to power all of that growth. However, biologists don’t yet understand the full picture of how egg cells become so large. A new study in fruit flies, by a team of MIT biologists and mathematicians, reveals that the process through which the oocyte grows significantly and rapidly before fertilization relies on physical phenomena analogous to the exchange of gases between balloons of different sizes. Specifically, the researchers showed that “nurse cells” surrounding the much larger oocyte dump their contents into the larger cell, just as air flows from a smaller balloon into a larger one when they are connected by small tubes in an experimental setup. “The study shows how physics and biology come together, and how nature can use physical processes to create this robust mechanism,” says Jörn Dunkel, an MIT associate professor of physical applied mathematics. “If you want to develop as an embryo, one of the goals is to make things very reproducible, and physics provides a very robust way of achieving certain transport processes.” Dunkel and Adam Martin, an MIT associate professor of biology, are the senior authors of the paper, which appears this week in the Proceedings of the National Academy of Sciences. The study’s lead authors are postdoc Jasmin Imran Alsous and graduate student Nicolas Romeo. Jonathan Jackson, a Harvard University graduate student, and Frank Mason, a research assistant professor at Vanderbilt University School of Medicine, are also authors of the paper. A Physical Process In female fruit flies, eggs develop within cell clusters known as cysts. An immature oocyte undergoes four cycles of cell division to produce one egg cell and 15 nurse cells. However, the cell separation is incomplete, and each cell remains connected to the others by narrow channels that act as valves that allow material to pass between cells. Members of Martin’s lab began studying this process because of their longstanding interest in myosin, a class of proteins that can act as motors and help muscle cells contract. Imran Alsous performed high-resolution, live imaging of egg formation in fruit flies and found that myosin does indeed play a role, but only in the second phase of the transport process. During the earliest phase, the researchers were puzzled to see that the cells did not appear to be increasing their contractility at all, suggesting that a mechanism other than “squeezing” was initiating the transport. “The two phases are strikingly obvious,” Martin says. “After we saw this, we were mystified, because there’s really not a change in myosin associated with the onset of this process, which is what we were expecting to see.” Clustered fruit fly nurse cells squeeze their contents into a large egg cell. Credit: MIT Martin and his lab then joined forces with Dunkel, who studies the physics of soft surfaces and flowing matter. Dunkel and Romeo wondered if the cells might be behaving the same way that balloons of different sizes behave when they are connected. While one might expect that the larger balloon would leak air to the smaller until they are the same size, what actually happens is that air flows from the smaller to the larger. This happens because the smaller balloon, which has greater curvature, experiences more surface tension, and therefore higher pressure, than the larger balloon. Air is therefore forced out of the smaller balloon and into the larger one. “It’s counterintuitive, but it’s a very robust process,” Dunkel says. Adapting mathematical equations that had already been derived to explain this “two-balloon effect,” the researchers came up with a model that describes how cell contents are transferred from the 15 small nurse cells to the large oocyte, based on their sizes and their connections to each other. The nurse cells in the layer closest to the oocyte transfer their contents first, followed by the cells in more distant layers. “After I spent some time building a more complicated model to explain the 16-cell problem, we realized that the simulation of the simpler 16-balloon system looked very much like the 16-cell network. It is surprising to see that such counterintuitive but mathematically simple ideas describe the process so well,” Romeo says. The first phase of nurse cell dumping appears to coincide with when the channels connecting the cells become large enough for cytoplasm to move through them. Once the nurse cells shrink to about 25 percent of their original size, leaving them only slightly larger than their nuclei, the second phase of the process is triggered and myosin contractions force the remaining contents of the nurse cells into the egg cell. “In the first part of the process, there’s very little squeezing going on, and the cells just shrink uniformly. Then this second process kicks in toward the end where you start to get more active squeezing, or peristalsis-like deformations of the cell, that complete the dumping process,” Martin says. Cell Cooperation The findings demonstrate how cells can coordinate their behavior, using both biological and physical mechanisms, to bring about tissue-level behavior, Imran Alsous says. “Here, you have several nurse cells whose job it is to nurse the future egg cell, and to do so, these cells appear to transport their contents in a coordinated and directional manner to the oocyte,” she says. Oocyte and early embryonic development in fruit flies and other invertebrates bears some similarities to those of mammals, but it’s unknown if the same mechanism of egg cell growth might be seen in humans or other mammals, the researchers say. “There’s evidence in mice that the oocyte develops as a cyst with other interconnected cells, and that there is some transport between them, but we don’t know if the mechanisms that we’re seeing here operate in mammals,” Martin says. The researchers are now studying what triggers the second, myosin-powered phase of the dumping process to start. They are also investigating how changes to the original sizes of the nurse cells might affect egg formation.

A team of researchers has rediscovered a frog species that had not been seen in over 130 years. First described in 1902, Alsodes vittatus had remained undetected despite numerous search efforts. The researchers found two separate populations of the species in the southeastern area of the historic Hacienda San Ignacio de Pemehue, located in Chile’s La Araucanía Region. This rediscovery marks a significant milestone for South American herpetology and highlights the importance of conserving biodiversity in the Southern Cone. A male individual of Alsodes vittatus. Credit: Edvin Riveros The frog Alsodes vittatus is an elusive creature, described in 1902, it remained undetected for more than a century. Now, after a decade of investigation, a research team has rediscovered it in its first confirmed sighting in 130 years. Researchers from the Laboratory of Systematics and Conservation of Herpetozoa (SyCoH) at the University of Concepción, Chile—Dr. Claudio Correa, renewable natural resources engineer Edvin Riveros Riffo, and biologist Juan Pablo Donoso—have published their extraordinary discovery in the journal ZooKeys. The habitat of Alsodes vittatus. Credit: Edvin Riveros A Historical Mystery Revisited Alsodes vittatus was scientifically described in 1902 by Rodulfo Amando Philippi, a German naturalist living in Chile. French entomologist Philibert Germain had discovered the species in 1893 at the former Hacienda San Ignacio de Pemehue in La Araucanía Region, Chile, and brought three specimens to Philippi for description. Since then, no one has seen the species again, despite multiple search efforts. A male individual of Alsodes vittatus. Credit: Edvin Riveros Between 1995 and 2002, several researchers unsuccessfully tried to find it in the Pemehue area, at the northwestern end of the former estate. In 2015 and 2016, new expeditions led by Claudio Correa and Juan Pablo Donoso managed to locate two populations of Alsodes in the same area, but the individuals they saw lacked A. vittatus’ distinctive white or yellow stripe on the back, suggesting they likely belonged to a different species. “The main challenge in locating it was the lack of precision in the description of its type locality,” say the researchers. “In Germain’s time, the Hacienda San Ignacio de Pemehue was an estate of enormous size, and the naturalist did not specify the exact place where he collected the specimens.” The habitat of Alsodes vittatus. Credit: Edvin Riveros Reconstructing the Past to Locate the Present To locate the species, Correa and his team had to reconstruct the route that Germain could have followed within the estate by studying his publications and other historical documents. In 2023 and 2024, Claudio Correa and Edvin Riveros followed the reconstructed route, entering the former estate from the southeastern end. There, they found two populations of A. vittatus in the Lolco and Portales river basins in La Araucanía region, confirming the existence of this enigmatic species after more than a century without records. This is an important milestone for South American herpetology and the conservation of biodiversity in the southern cone. Most of the other species in the genus Alsodes are either threatened with extinction or we don’t know enough about them to assess their status, and shedding light on where and how they live is the first step in protecting them.

Credit: Edvin Riveros “The rediscovery of A. vittatus allowed us to obtain, more than a century after its description, the first biological and ecological data on the species. Field observations also indicate that this amphibian faces several significant threats and that it could be considered endangered,” the researchers warn. “In a broader context, this rediscovery demonstrates the limited biological, evolutionary, and biogeographic knowledge of the amphibians that inhabit the southern cone of South America, emphasizing the urgency of their study and conservation.” Reference: “Lost for more than a century: the rediscovery of Alsodes vittatus (Philippi, 1902) (Anura, Alsodidae), one of the rarest and most elusive amphibians from Chile” by Claudio Correa, Edvin Riveros-Riffo and Juan P.
